To all whom it may concern:

Be it known that 1, ROBERT C. NEWTON, of Xeedham, in the county ofNorfolk and State of Massachusetts, ajcitizen of the United States, haveinvented a new and useful Improvement in Inking Appliances, of which thefollowing is a specification.

In printing telegraphic apparatus and other like machines where there isa. tape on which therecord is to be printed and a printing roller whichmust be kept properly inked to make the record, there have been variousproblems encountered in connection with the attempt to secure theapplication of the right amount of ink to the printing wheel with nodanger of an oversupply. Attempts have been made to secure the desiredresult by the application to an ink reservoir of a valve of the needletype which being screwed down so as to nearly close the aperture throughwhich the ink flows, is expected to allow only i the right amount of inkto pass. This has not been entirely successful for unless an air hole isprovided the ink will 11Gb flow freely and the air hole allows aconstant leakage of ink. When in the use of such a device the printinwheel is at rest perhaps for some considerable period of the day the inkis constantly leaking and causes an oversupply of ink on the printingroll and the blotting of the paper when the roller next attempts toprint. A brush has been used for the purpose which brush has been putinto the outlet of an ink reservoir and engages the printing roller.Here again the brush which may be of felt or the like becomes saturatedunless there is a sufficient drain from it consequent upon the continueduse of the printing wheel. Another means for inking the printing wheelis a felt. roller which rides on the wheel. This. however, is usuallykept which the ink is daubed upon the roller by hand and this requiresconstant care on the part of the attendant.

My invention is intended to provide a means for inking a printing wheelwhich is adjustable so that the right amount of ink may be distributedand which also may be closed when it is desired to remove the device forrefilling.

My invention will be understood by reference to the drawings in wh1chFigure 1 is a Side elevation of my inking device upon a somewhatenlarged scale, Fig. 2 being a vertical section taken at right angles toFig. 1, and Fig. 3 is a detailof the lower end of-my inker to indicateits adjustment. I

In the drawings I have shown merely a portion of a registering device ofthe general character above referred to, A being a frame mounted upon abase B.

C is a paper'tape of the usual character upon which the registry is tobe made and a which is supplied'from a suitable reel as is customary 111such lcvices.

'D, D are apair of feed rolls (a portion only of the roll I) beingshown), between which the strip of paper C runs and by which it is drawnoff the reel, (7, I]. being guides under which it is drawn.

E is the printing roll mounted on a shaft 0 and operated by any suitablemeans. Below it is a platen roll E which is free to turn as occasion mayrequire. The tape of paper runs between these two rolls also and thereis given to the platen roll E a vertical movement from time to time toimpress the paper tape C against the printing roll E.

My. inking device is pivotally attached to the frame A by means of anarm, a, a being its pivotal attachment, as shown a screw. My ,inkercomprises a hollow cylinder F the lower end of which is fiat. on itsexterior. The chamber formed within the cylinder F is provided with asloping or conical'floor f at the apex of which is a small opening fThecylinder F is provided with a screw top F} having an air hole fsufficient in size to supply the slight amount of air necessary tocompensate for the draft on the ink contained in the cylinder F and soprevent a vacuum. Down through the center of this cover F is a threadedopening within which screws a needle valve or plug G which is threadedon its exterior at its upper end to fit into the opening in the cover Fits lower end 9 being pointed seas to fit into and close the hole f atthe lower endzof thechamber F when desired. The top F Screwspnto the topof the cylinder F and is adapted to be removed when it is necessary tofill the chamber within the cylinder.

The lower end of the cylinder carries a collar H which is threaded onits interior so that its upper end may screw upon the threaded lower"end of the cylinder F. The threads in the collar H extend throughoutits length and into the lower end of the collar H is screwed a plug Jmade of felt or other like substance which will absorb the ink ' collarII is screwed up tight so as to close the opening 1 by means of the plugJ, In

, Fig. 2 there is a free opening for the ink to pass out into the spacej between the top of .,the plug and the bottom of the cylinder and thespace becomes a saturating reservoir for the ,plu hence the plug willink the printingroller freely as may be required at cer-. .tain tunes inthe day. During the times when the apparatus 18 not so frequently in useso that the printing roller requires less the collar H is screwed uptight carrymg the plug J with it. into the position shown in Fig. 2where it closes the opening j, thus preventing any waste .of ink andalso preventing the too frce'inking of the vprinting roller and theconsequent blotting of the tape when the printing operation againbegins. This plug therefore serves the double purpose of an inking padand also of a plug to check the flow of ink. The arm a allows thecylinder perfect irecdoniof movement so that the device will always reston the printing roller whatever may be the position of the plug J.

The embodiment of my invention shown in the drawings is simple, but I donot mean to confine myself entirely to it as my invention may beotherwise embodied, variations in the shape and general construction ofits various parts being possible without departing from the spirit ofthe invention which relates to -the adjustment of the ink flow by' thelocation of the pad by which the print ing roller is inked. Theapparatus is intended to be used with the ord nary ink used in suchdevices, the air hole furnishing sufficient air inlet. to allow the inkto flow out as needed. t

hat I claim as my invention is 1. An inker comprising an ink reservoirhaving an outlet through which ink can flow, and a pad, and means formoving said pad away from said outlet to form a space to receive andhold ink to saturate said pad and to "ard said outlet torestrict suchsaturation, as set forth. a

An inker comprising an ink reservoir having an outlet through which inkcan flow, a pad and means for connecting said pad to said reservoiradapted to inclose a chamber one wall of which is formed by said pad andinto which said outlet opens to supply said ink thereto, said meansbeing movable to close said pad against said outlet. 3. An inker forprinting rollers comprising a cylinder containing an ink reservoir, anoutlet at the bottom thereof, means for closing said outlet and a padlocated to receive ink from said outlet and movable to ward and fromsaid outlet whereby it may serve to control the passing of ink from saidoutlet.
